METHOD OF BURNISHINGEHE INTERIOR OF CORN COB PIPE BOWLS Harry Hirsch], Washington,-Mo. Application November s, 1933, Serial No. 697,228

9 Claims.

This invention pertains to a new and novel 1 I0 cient method whereby the inner surface of a corn cob pipe bowl when formed in its natural condition may be subjected to a series of simultaneously projected flames, thereby burning off the fuzz, peth and uneven portions thereof; properly .15 burnishing said inner surface, and breaking in the pipe for its initial use.

It 'is universally agreed by all corn cob pipe smokers that there is a disagreeable taste or flavor experienced the first time it is smoked, and

Y20 that the pipe smokes sweetest after it is broken in, and that heretofore the pipes had to be broken in by the burning tobacco singeing or carbonizing the inner surface of the bowl which required a series of smokes.

Another object of this invention is to so dispose the corn cob bowl with relation to the flame I projecting means that it may readily be turned by hand so that the flames will reach and properly burnish substantially the entire inner surface of said bowl, and at the same time the said inner surface is pressed against the outer metallic surface of a metallic nipple so as to provide said inner surface with a smooth finish.

A further object of the invention is to daub or swab the inner surface of the corn cob pipe bowl after it has been properly burnished and smoothed with an aromatic liquid or extract which further improves the breaking in of the pipe.

The foregoing and such other objects as may appear from the ensuing description are attained by certain steps herein set forth and means for carrying out my invention, the means disclosed by the annexed drawing constituting but one of the various mechanical forms by which the principle of the invention may be applied.

In the accompanying drawing forming a part of this specification it will be seen that:

Figure 1 is a sectional elevation of my novel burnishing device, showing one form of means by which my new method of burnishing may be carried out, the same being represented in connection with a corn cob pipe bowl in position to be burnished, and showing in full lines the end portion of a suitable torch.

of the dotted lines 2-2, Fig; 1, and

Figure 3 is an elevation of the nipple removed or detached from its support, showing a series of openings of different formations or shape through which a series of flames are projected into contact with the inner surface of the pipe bowl.

Referring now to the means employed in connection with my improved method of burnishing the interior surface of corn cob pipe bowls,

as illustrated in Fig. 1 of the drawing, it will be seen that the numeral 1 designates a'metallic plate broken away, said plate being provided with a screw-threaded opening formed therethrough, and within said opening is fixedly secured a metallic nipple 2, which has a circular formation, with a hollow central portion extending from its outer screw-threaded end portion 3 secured to said plate, to its inner solid and closed end portion 4, the wall of said nipple having a series of openings 5 of different formation and contour formed therethrough for the purpose hereinafter described. Adjacent the open end of the nipple 2'issuitably placed a gas or other suitable torch from the outer end portion 6 of which is projected a voluminous flame which is adapted to be projected into the nipple and through the series of openings formed therethrough into contact with the inner surface of the corn cob pipe bowl '7 surrounding said nipple, thereby burnishing substantially the entire interior surface of the bowl by burning and carbonizing its surface as the bowl is slowly rotated by hand.

It will be understood that when a corn cob pipe bowl is formed in its natural condition, its inner surface is more or less rough and uneven, owing to the material from which it is composed, and includes fuzz, fibres and peth formations, which are removed and destroyed by my improved 3 method which serves to simultaneouly project a series of flames into contact with the inner surface, and at the same time the pipe bowl is slowly rotated by hand so that the flames will burn over and contact with the entire inner surface, thereby burning off all of the fuzz, peth and uneven surfaces, and by further rotation and pressing of the bowl in contact with the outer metallic wall of the nipple the said inner surface will be furnished with a smooth finish and a properly burnished appearance, after which an aromatic extract or liquid is applied to said surface by any desirable means, thus providing a broken in corn cob smoking pipe that will smoke sweet the first time it is used.

Figure 2 is a cross-section taken in the plane I While, as shown in the drawing, the nipple is provided with a series of perforations and slotted openings formed through its wall, it will be readily obvious that any desired form of openings may be utilized, provided they serve to permit the projected flames to reach the entire inner surface of the bowl so that said surface will be properly burnished to insure that it has been thoroughly broken in and ready for the first sweet agreeable smoke.

It will be understood that the flame projected into and through the walls of the nipple 2 will serve to heat the said nipple to a comparatively red heat, hence, as the bowl is turned and pressed into contact with the outer surface of the hot wall of the nipple, the more complete, uniform and smooth burnished surface of the inner surface of the corn cob pipe bowl is accomplished.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

-' '1. The method of burnishing the inner surfaces of a corn cob pipe bowl when formed in its natural condition by subjecting the inner wall surfaces of said bowl to a series of flames projected simultaneously into direct contact with said surfaces only.

2. The method of burnishing the interior upright surface of a corn cob pipe bowl when formed in its natural condition by subjecting said surface to a series of different forms of flames projected simultaneously into direct contact with said interior upright surface only.

3. The method of burnishing the interior surface of a corn'cob pipe bowl when formed in its natural condition by subjecting said surface to a series of flames projected simultaneously into contact therewith, and then swabbing the burn- .ished surface with an aromatic extract.

.right surface of a corn cob pipe bowl when formed in its natural condition by subjecting said surface to a series of flames simultaneously projected into contact therewith during a rotary movement of said bowl, then smoothing the burnished surface by pressing said upright surface against a metallic surface, and then applying an aromatic liquid to its burnished surface.

6. The method of burnishing the inner surface of a corn cob pipe bowl when formed in its natural condition by subjecting said surface to the action of a series of flames projected simultaneously into contact therewith during a rotary movement of the bowl, then smoothing the surface by a continued movement and pressure contact with a metallic surface, then applying an aromatic liquid to the surface.

'7. The method of burnishing the interior surface of a corn cob pipe bowl when formed in its natural condition by subjecting said surface to the action of a series of flames of different formation projected simultaneously into contact therewith during a rotary movement imparted to the bowl, then smoothing the surface by further rotary movement and pressing contact with a metallic surface, and finally applying an aromatic extract to the burnished surface.

8. The method of burnishing the inner upright surface of a corn cob pipe bowl, consisting in projecting a flame into the interior of a nipple and through the walls of said nipple until it is highly heated, then rotating and pressing said bowl against the metallic wall of said nipple to furnish a smooth burnished finish to said inner surface and then applying an aromatic extract to the burnished surface.

9. The method of burnishing the inner upright surface of a corn cob pipe bowl, consisting in projecting a flame Within the interior of a metallic nipple until the Walls of the nipple attain substantially a red heat, then surrounding the nipple with the corn cob pipe bowl, rotating and pressing the bowl against the outer hot surface of the nipple to furnish a smooth burnished and finished wall surface to the interior of said bowl and finally applying an aromatic liquid to said ans
